Question

write the equation of the line which passes through (5 -2) and is parallel to x=4

Answer 1

anything parallel to x = 4 will be of the form x = k where k is any number

ex: x = 22 and x = 9 are parallel to x = 4

Answer 2

but we must force the line to go through (5, -2)

so how do we do this?
